New educational software for teaching the sunpath diagram and shading mask protactor | 1997 | English
The well-known versions of the sunpath diagrams that appear in the AIA’s Architectural Graphics Standards are based on the equidistant sky dome projections and use a shading mask protractor developed by Olgyay and Olgyay at Princeton University in
The lighting simulation programme Radiance is used to predict daylight factors and the illuminance distribution in a room which is 12m x 12m x 3.6m high, with grey tinted solar control glazing.
Since two years, the Dutch building consultancy practice has been supported by an integrated design environment to base its advices on.
Building thermal models reduction: improving exixting methods by taking spectral imputs characteristics into account | 1997 | English
Modal-based model reduction techniques have been modified in order to improve their performance when applied to building thermal models.
Evaluation of the finite control volume method in simulating thermal fire resistance of building elements | 1997 | English
Application of the finite control volume method on simulating thermal fire resistance of building materials and elements was evaluated. Example was taken on studying the thermal responses of a concrete column under fire.
This paper discusses a multi-year (MY) approach to building energy simulation and presents a pilot study in Hong Kong that investigates long-term building energy performance using MY weather data. Building energy simulations in the pilot study wer
Collaborative building engineering is a team effort in which many elements have to be combined into a unified structure. The aims of the architect, the engineer and all the other players have to merge into a seamless design process.
This paper describes the use of daylight coefficients in a computer tool which is based in Monte Carlo backward ray tracing merthod and was developed under the frame of DAYLIGHT- Europe EC Project.
Influence of modeling uncertainties on the simulation of building thermal comfort performance | 1997 | English
In this paper, the parameters in a building thermal simulation model are tracked, which are subject to modeling uncertainty, i.e. uncertainty arising from commonly applied physical assumptions and simplifications.
This paper reports the first results of an ongoing project aimed at generating design information /knowledge for wet central heating (WCH) refurbishment in multi-family houses in Central Europe.
Energy saving in office buildings: a case study in Rome through the use of DOE-2 and other simulation tools | 1997 | English
A large office building has been the object of a detailed feasibility study in order to select the most effective actions for energy saving in space cooling. Actions concerning the modification of building envelope layout, including materials, sha
Moisture permeability data presented as a mathematical function applicable to heat and moisture transport models | 1997 | English
The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process.
CA-SIS software has been developed on PC as a tool for engineering offices in their Heating, Ventilating and Air Conditioning studies.
A controller for heating systems is normally equipped with many facilities to make it flexible and the heating system more cost-efficient. This results in a number of input parameters to be given by the user.
Combined conduction-convection-radiation heat transfer in concrete block walls with one or two cavities is simulated using the CFD code “FIDAP”.
This paper briefly reviews recent research into the modelling of complex fenestration systems, before presenting some results obtained by the use of a new (developing) simulation model, utilising Monte Carlo Methods and Geometric Optics (ray traci
Dynamic link of light- and thermal simulation: on the way to integrated planning tools | 1997 | English
A method to evaluate the energy demand for lighting on an hourly basis is presented. The method is based on a raytracer and a dynamic modelling of the sky’s luminance distribution.
Methodology for modelling/simulation of an office building equipped with an air-condicioning system | 1997 | English
This article presents a study of a building-equipment coupled system performed at the Gaz de France R & D Division. The commercial building under study is equipped with an air-conditioning installation which includes a gas-fired dual-seJVice a
